Python问题：RuntimeWarning: invalid value encountered in reduce return ufunc.reduce(obj, axis, dtype, o

今天在用气象数据的过程中python报错

D:\python366\lib\site-packages\numpy\core\fromnumeric.py:83: RuntimeWarning: invalid value encountered in reduce
  return ufunc.reduce(obj, axis, dtype, out, **passkwargs)

尝试过多种方法不能解决，后来发现是csv文件有错误。
